Reclaiming Process for Scrap Deuterated Polyethylene (Cd sub 2 ).

摘要

A laboratory version of a process to clean contaminated deuterated polyethylene (CD sub 2 ) was modified slightly and scaled up to produce 2lb of clean,reusable CD sub 2polymer. A complete cycle of the process is: (1) Melt the CD sub 2polymer at 30vol percent in xylene at 105to 110exp 0 C. (2) Pressure filter the hot solution at 103to 138kPa (15to 20psi). (3) Cool the solution to precipitate the polymer and separate it from the liquor. (4) Vacuum dry the precipitate at about 266Pa and 37exp 0 C. (ERA citation 01:026228)
